I own a pair of Tannoy D500 Series 2 for nearly 20 years now. Still sound great, lately collaborating with a newly revised Quad 303.
Now my Tannoys need a refoaming, see pics. First action: have a look inside to learn what's inside, and what to order. My problem: I can't get the speakers off the front panel. All four screws were removed easily, but both concentric and bass unit won't move a bit.
Accessing it from the bottom plate or the crossover panel failed, because the damping material (foam) cannot be removed from there.
Any ideas how to proceed?

Take a bolt which is slightly larger in diameter than a vacant mounting hole and tap it into the metal. You may then obtain enough purchase on pulling the bolt to start lifting the driver from its seating. It is probably stuck in place by a gasket of some sort.
Good tip- or get a spudge in plastic/Nylon to get some leverage. Careful with the wood... There is quite a large gasket of foam on the back of these drivers that has probably stuck after all these years.
Don't know what thickness the front panel is but on my tannoy actives it was 3 cm, and rebating them worked wonders in the mids for the dual concentric see: chamfering driver holes.
Last thing i beleive WD 40 would dissolve the glue between cone and suspension, i once had the stupid idea of cleaning the cone with it to make it shine and I'm pretty lucky i did not use more. To be confirmed.
Thanks, still trying to find something suitable. Mounting hole diameter is a bit more than 6 mm, so an M7 is certainly too much.
Tried an M6 with some tape, but this combination does not deliver enough friction. Working on it.
You could also place a small flat blade screwdriver inside the vacant mounting hole and gently try to lever the driver out from within the hole.
A suitably padded object of the appropriate height would have to be placed carefully on the wood surface to provide the necessary pivot point or fulcrum for the screwdriver.
The idea, of course, is to protect what is likely a real wood veneer finish at all costs. And, also to that end, I'd be very wary of applying WD40.

Thanks, found something better: it turned out that my Philips screw driver fits *exactly* in the mounting holes. Half a minute of gently increasing movements loosened the speaker. So far, so good.
Meanwhile I'm in contact with an England based company offering Tannoy service. They doubt that exactly the parts needed will still be available. Also I was told that they usually solve that kind of problem with shoe repair glue from the back side, if they can't get spare parts.
Has anyone some experience doing so? At least this sounds like a temporary patch until I find suitable spare parts.
Maybe I'll contact Tannoy service directly for parts.
Look for something identical to this stuff: Granville Black Silicone Sealant 40g | Halfords UK
I've used it on surrounds such as yours. It sets flexible, just like a new layer of rubber. Not to be confused with ordinary silicone sealant!
P.S. Glad your screwdriver trick worked! 😎

You may be able to use RooGlue clear to mend the surround. That effectively upgrades foam surrounds.
This really sounds interesting. Let's see whether it's available on the continent. Thank you!
Thank you for this hint, yet on their website they do not say that RooGlue stays flexible after drying. So I'm not really confident that this is appropriate in my case.
And by the way, the surrounds are rubber, not foam.
After cleaning with alcohol and lint free cloth, use rubber cement or butyl caulk on the surround.
Never heard of 'rubber cement' or 'butyl caulk' before, but these seem to be the products to look for - thanks a lot!
You could try reaching out to this guy:

He claims to be able to produce sizes not readily available.

Ahh, interesting! I'm checking out ebay offers frequently, yet never found this shop. Thank you!
Ok so far! He did not have surrounds for my speakers on his ebay shop, but put one up on my request. Bought a kit of 4 surrounds including glue and solvent for 65 Euros.
Now I'm really looking forward to delivery. Will keep you informed. Thanks for your support so far to all of you, and have a nice weekend!

Hmm - sicken4you @ ebay delivered foam surrounds instead of rubber. Optically, I don't like them. These are greyish instead of black.
What's your opinion regarding the acoustic properties?

Changing to foam may result in an entirely different response characteristic.
It's a gamble that may, or may not, pay off.
I would try to repair the tears in the rubber surrounds first - nothing to lose in doing so!
